1. Localisation of the brainstem nuclei: the open book concept
Domina Petric, MD

2. ˝Open book concept˝ (suggestion of the name by Domina Petric, MD; inspired with Leonard E. White on-line lectures)
Somatic motor and branchial motor nuclei are the closes to the midline of the brainstem.
Visceral motor nuclei are lateral from somatic and branchial motor nuclei.
Visceral sensory and special visceral sensory nuclei are more lateral than visceral motor nuclei.
Somatic sensory and special somatic sensory nuclei are the most lateral nuclei in the brain stem.

3. Chapter one: mesencephalon (the midbrain)

4. Oculomotor nerve, trochlearis nerve
Oculomotor nucleus is somatic motor
nucleus. It is close to the midline of
the mesencephalon (middle of the book).
Edinger
Westphal
nucleus
(III. nerve)
is visceral
motor nucleus.
It is lateral
to the somatic
motor nucleus
(˝written˝ on
the pages of
the book).
Trochlear nucleus is
somatic motor nucleus.
It is close to the midline
of the mesencephalon
(middle of the book).

5. II.
Chapter two: pons

6. V., VI., VII. and IX. nerve Trigeminal motor nucleus is branchial
Abducens nucleus
is somatic motor
nucleus.
Superior salivatory
nucleus (VII.) is
visceral motor
nucleus.
Facial nucleus
is somatic motor
nucleus.
Inferior salivatory nucleus (IX.)
is visceral motor nucleus.

7. Chapter three: medulla oblongata
III.
Chapter three: medulla oblongata

8. VIII., IX., X., XI., XII. Nucleus amgiguus has branchial motor
Cochlear and vestibular nuclei are
extending from the inferior portion
of the pons to the medulla oblongata:
special somatic sensory nuclei.
Close to the edge of the book paper.
VIII., IX., X., XI., XII.
Nucleus amgiguus
has branchial motor
part (IX., X.)
and visceral
motor part (X.)
Hypoglossal nucleus is
somatic motor nucleus.
Dorsal motor nucleus of vagus
is visceral motor nucleus.
Nucleus of the
solitary tract
(VII., IX., X.)
is visceral
sensory nucleus.
Spinal accessory nucleus is
branchial motor nucleus.

9. IV.
Chapter four: the longest nuclear complex of the brain stem and the most lateral one.

10. Trigeminal complex of the brainstem is general sensory nucleus complex.
Mesencephalic nucleus (V., VII.) has for example
cells sensitive to the stretch in our jaw muscles,
in our temporomandibular joint.
Those cells are very important to govern
chewing behaviour.
Main sensory nucleus or principal trigeminal
nucleus (V., VII., IX., X.) recieves for
example signals
about light touch from the face.
Spinal trigeminal nucleus (V., VII., IX., X.):
pain and temperature.
